Digital outputs
Each unit has 4 floating digital outputs. Like the digital inputs, these are distributed
onto the two 25-pin sub-D socket (relay 1-4).
Using the digital outputs, you can switch external devices, for example, to report sys-
tem errors. The respective events are created and set up accordingly in the G-Set
configuration software.
Assignment of 25-pin Sub-D connectors
The contacts can be soldered directly to the corresponding Sub-D plug. The assign-
ment of the 25-pin Sub-D connectors is shown in the following figure.
